教學建議（Suggested teaching notes）
一、教學內容分析
本單元是一個複習單元，主要幫助學生複習鞏固第十五-十八單元所學的內容。具體的教學內容安排如下：
（一）第73課通過問答、操練及寫的練習形式複習數字和一般現在時的被動語態用法。（二）第74課的課文是一篇介紹宇宙和人造衞星的文章，以此來複習數字和被動語態的用法，並學習一些詞彙和短語。
（三）第75課提供了問答練習，單詞與詞組替換練習及選詞填空練習，通過這些練習來進一步複習鞏固表達距離（路程）的句型及一些常見詞語的用法。
（四）第76課是由聽力練習、構詞法知識小結、操練及寫的練習四個部分組成。這一課進一步複習與第75課內容相關的詞語用法，學習構詞法的一般知識，鞏固帶情態動詞的被動語態用法和利用本單元所學詞語完成一篇短文的寫作練習。
二、教學方法建議
（一）語法複習
本單元主要的教學目的是複習第十五一十八單元所學的語法項目，可以綜合運用這幾單元的材料和教學方法，同時也要在此基礎上採用其它新的教學方式、方法，以便學生能歸納總結所學語法知識。
1．複習有關數字的表達方法
第 73課Ask and answer可讓學生做快速的連鎖問答，使他們熟悉句型和數字，並達到脱口而出的熟練程度。為了給學生創造更多的機會，教師可提供火車列車時刻表中全國各主要城市間的距離表或世界各地航空路程表，將其放大製成掛圖，貼在黑板上。第75課Ask and answer可用同樣的材料進行課堂練習活動。待學生練熟課本上的句型後，要適時插入練習冊第73課的練習1。其中的重要句型是：
1）How many kilometres by train is it from… to…?
2）How far away is… from…?
3）How many kilos of milk was produced on Green Lake Farm last year?
4）What about 1996?
5）53,500 kilos 5,100 kilos more was produced than last year.
教師要求學生用自己的詞填入空缺的部分，用其它詞替換句型中劃線部分，這樣可以造出許多句子，而且還可以事前複習或預習下面練習和課文中出現的詞語。例如：
1） How many li by air is it from… to…?
2） How far away is the earth from the moon?
3） How many TV sets were sold in the shop last year?
4） What about 1996?
5） 213 sets. 47 sets more（less） were sold than last year.
練習表示數量的方式有許多種，例如教師將一摞書帶到課堂上，讓學生猜每本書的頁數。做這樣的對話：
T: How many pages do you think this book has?
S1: I think about 120.
T: NO. The number is too small.
S2: What about 500?
T: Oh, that's too big.
S3: How about 250?
T: That's quite right. 265.
在第一冊和第二冊中，我們已經陸續學習了數字的用法，教師可幫助學生回憶它們的念法，並做快速連鎖問答。還可就長度、高度、重量等做問答，例如：How long is the Yellow River?How heavy is your bag? How tall／high is that tree?等等。
2．被動語態的複習
本單元第73課Practise和Write；第76課Practise，練習冊第73課練習2、3都是被動語態的複習練習。第十五至十八單元的語法重點是被動語態。學生在這4個單元的學習中已基本瞭解了被動語態的各種構成和用法，而本單元複習和主要目的是引導學生對這一語法項目進行歸納總結，並提高他們綜合運用該語法知識的能力。建議教師將本單元及練習冊中的相關內容進行重新組合和調整，避免照搬前4單元的教學路子，提高學生的學習興趣，進而提高他們綜合運用語言的能力。
教師讓學生先口頭操練第73課Practise，此時將練習冊第73課練習2也轉換成類似課本上 Practise的形式，例如：
Workers make watches in Guangdong.
Workers produce TV sets in Fujian.
People produce fridges in Beijing.
People produce keys in the factory.
學生通過全班、半班、兩人小組的口頭練習後（將陳述句轉為被動語態，再轉入下一個句型操練（回答What is／are… used for?）。教師提供如下的提示：
1）telling the time 2）watching TV programmes 3）keeping food fresh 4）opening and locking doors 5）making clothes 6）selling and eating 7）sending people 8）making glasses and other things 9）giving people food 10）sending letters
兩個練習所涉及的物品的用途都包括在這些提示中。學生經過反覆操練能夠完全熟練掌握該句型，教師可引導他們説同一物品的多種用途或談論其它物品的用途。例如：Radios are used by old people for listening to the news and music.
Radios are used by policemen for sending and receiving messages.
Radios are used by students for learning English.
在充分口頭操練的基礎上，完成第73課的Write練習也就不難了。在操練第76課Practise時，教師也應啟發學生的思維，造出符合生活實際情況的、帶情態動詞的被動語態句子。這個練習完全可以限制在已有詞彙範圍內，誰造的句子越多，誰將得到表揚。
Your room must be kept clean and tidy.
Older people must be given seats on a bus.
The tree must be watered often.
練習冊第73課練習3是個很好的綜合練習。學生完成填空後，教師仍可讓他們對照圖畫，複述這段對話，以達到鞏固的目的。
（二）閲讀教學
本單元第74課是一篇題為“The universe and man-made satellites”的課文，是一篇科技小品。為了引起學生的閲讀興趣，建議讓學生帶着問題有目的地閲讀，或在閲讀前讓學生猜測課文內容，然後再閲讀課文證實他們的猜測。具體做法是：
1．學生們討論練習冊第74課練習1中的問題，並試着回答這些問題。
2．教師根據每個自然段內容，設置如下概括性問題：
1）What do we mean when we talk about the universe?
2）Do you know anything about the moon? Try to say something about it.
3） What is a man-made satellite? What's it used for?
4）Please say something about people's knowledge of the universe.教師可將學生們的回答簡單地板書在黑板的一側。然後讓他們打開書閲讀課文。學生們閲讀後，教師帶着他們驗證猜測。在這個過程中，實際上教師是在讓學生熟悉本課的大意，並接觸課文中的句型和詞語。教師在黑板的另一側板書課文中的關鍵詞，與學生們的猜測答案相對照。下一步讓學生逐段複述課文。反覆數次後，做練習冊第74課練習2。學生在對證這個練習答案的過程中，又複習了本課的詞語，掌握了與課文內容相關的新表達方式。這樣他們完成練習3、4也就不難了。學生完成了練習2、3、4後，教師可繼續讓他們將這3個練習中的語句與課文作比較，找出異同，例如：
1）課文-Many of the stars cannot be seen because they are too far away.
練習Many of the stars are so far away that we cannot see them.
2）課文-The moon travels round the earth. It is our satellite.
練習The moon, our satellite, travels round the earth.
在這種比較過程中，學生又一次熟悉了課文內容及詞語，特別是被動語態的用法。與此同時也鍛鍊了他們的思維能力，認識到英語語言表達靈活的特點，為下一步的詞彙教學做好輔墊。
本單元配套《閲讀訓練》的內容，由一篇短文和小韻詩組成。短文的體裁和題材與課文相似，可作為課文教學的補充材料。這一部分的詞彙量是288個。
（三）詞彙教學
本單元的詞彙大部分出現在閲讀課文之中。詞彙練習主要由兩部分組成。第一部分是一組有關選擇電視節目的對話及詞語練習。第二部分是構詞法的部分知識。
1．對話及詞語練習
本單元第75課Practise和Choose the right words及練習冊第75課練習1、 2都是有關選擇電視節目的對話練習。練習冊第75課練習3和第76課練習3分別是有關put和make詞組的練習。這些練習中生詞很少，只有兩個：enjoyable和channel。但討論選擇電視或電台節目的對話在教材中是第一次出現。
建議教師把課文第75課Practise和練習冊第75課練習2放在一起練習。首先，教師向學生展示電視和電台節目表，如下表。
TV: ramme for Children Radio: 1. Music World
2. 29-part Series: Family（2） 2. News Report
a Reports 3. Foreign Languages Magazine
es: Women ow on Chinese History
5. Chinese Programmes for Foreigners
c Bridge
etball Match (Beijing Vs Henan)
這兩個練習中的主要句型如下：
1）Which TV/radio programme shall we watch/listen to?
2）Which TV／radio programme do you think is more interesting/enjoyable?
3） Well, I don't think any of them is interesting/enjoyable.
4）I think I shall…instead.
5） Why don't you go and… instead?
6） Good idea. That is much better than….／… is better than….
學生看圖按全班、半班、兩人小組操練句型，直至熟練為止。然後全班進入下一個對話內容的學習，即課本第75課Choose the right words和練習冊第75課練習1。這兩個練習原本是寫的練習，但建議教師依靠圖片和角色扮演等手段，讓學生們先口頭熟悉對話內容，並採取各種形式進行口頭操練，然後再據此完成筆頭練習。教師應鼓勵學生積極思維，創造性地編出不同的對話。例如：
1) A: Which TV programme shall we watch? I can't decide.
B: Which do you think is more interesting?
A: Well, I think the children's programme is more enjoyable.
B: Which channel is it on?
A: It is usually found on Channel 3. Try that.
B: I've tried that. But I can't get it.
2) A: What are you doing?
B: I'm trying to find our favourite TV programme-sports.
A: Have you got it yet?
B: No. I don't know which channel it is on.
A：It must be on Channel 14. Try that.
B：OK…But this is not sports.
A: Well, I don't think any of the programmes is interesting. I think I shall listen to the radio instead. Why don't you join me? It must be more enjoyable.
2．構詞法
本單元主要介紹了構詞法中複合名詞；名詞變形容詞；動詞變名詞（結尾為er/or）的構詞形式。在教學構詞法知識時，教師可採取提供部分例詞，要求學生通過觀察自己總結出構詞規則的方式，讓學生對構詞法知識的認識從感性認識上升到理性認識，從而印象深刻，記憶牢固。
複合名詞的學習要結合練習冊第76課練習2。現根據上述構詞法將第一冊到第三冊中出現的有關單詞歸類如下：
複合名詞：afternoon baskeball bedroom birthday blackboard bookseller bookshop breakfast classmate classroom day-time doorbell Englishman fireplace football gate-keeper gateman grand-parents granddaughter grandson handbag headache headmaster headteacher hometown homework housework kilometre know-all loudspeaker mooncake motorbike northeast northwest pencil-box penfrlend photograph playground policeman postcard railway reading-room shopkeeper southeast southwest spaceship sunrise sunshine teapot teamwork volleyball weekday 名詞變形容詞：interesting surprising northern southern woolen
動詞變名詞（結尾-er/or）：
cleaner driver inventor keeper teacher speaker traveller visitor worker
（四）筆頭訓練
本單元設置了一些寫的練習，它們大多用來配合語法複習、課文教學和詞語教學。第76課最後一個練習Write是專門訓練寫作文的技能。寫的內容和所用句型和詞語都與第十五-十九單元有關。教師應引導學生複習這幾單元內容，然後再進行寫的練習。下面提供幾個例子。
1) My sister loves in France. Last week she sent me a postcard. She said that she had watched a very interesting program me on TV. It was sent to France from Japan by satellite. The program me was about twins. She liked it very much.
2) David lives in Oxford. Last week I got a letter from him. It said that he had heard a very interesting program me on the radio. The program me was about the old things in a museum and it was sent to Oxford from China by man-made satellite. He said that he enjoyed it very much.
（五）聽力訓練
本單元設置了一個聽力練習，即在第76課第一部分和練習冊第76課練習1。內容是有關幾個著名的宇航員的。為了降低聽力難度，在聽之前教師可出示有關宇航員的照片，並用英語作簡單的介紹，以引起學生的興趣，使他們有目的地捕捉聽力材料中的有用信息，最後逐步完成聽力練習。

Let the Ss read the passage carefully and then discuss their answers in pairs. Finally check the answers with the whole class.
Deal with any difficulties that the Ss have. They should be able to guess the meaning of new words such as knowledge and programme from the context, but tell them to use their dictionary where necessary.
You could give some more background information about spaceships without people: some spaceships have been sent to visit different planets, such as Mars, Venus and Jupiter.
If you wish, ask the Ss to write the answers to Wb Ex. 1 in their exercise books. The suggested answer to the last question is: With the help of the man-made satellites, it is easy for different countries to send and receive messages. We can also use satellites to help us make telephone calls to foreign countries.
